Yugi's Dark Story

Yugi was sold into slavery in his time period, however, was rescued by a mysterious girl around his age, in his time period, but she has a secret only Yugi knows. Can Yugi's friends and the Pharaoh trust her like Yugi does or will they think that is like her grandfather and try to help him in taking over the world? RATED M b/c I don't know how it turns out to be and i'm paranoid.
